Light micrograph of a pancreatic islet stained with an antibody to the major peptide hormone glucagon to show the relative content and distribution of the alpha, or A cells, which produce it. The antibody was labelled with a green fluorescent dye. One will note that there are a few fluorescent cells, outside the islet, that stain one of the three colours. These are either isolated islet cells that 1) are not confined to the islet, 2) belong to an islet almost entirely outside the plane of the section, or 3) are an artefact of sectioning, which was done on frozen tissue.
